Uneven temps. Rising bills. Condensation. Drafts. If any of these sound familiar in your home, pole barn, or commercial building, your insulation is the problem.
Driftless Foam is your dedicated spray foam insulation specialist, delivering expert installation with premium materials every single time.
Traditional insulation leaves gaps. Spray foam doesn't. It expands on contact, sealing every crack and void to block heat, eliminate drafts, and shut out moisture in one step.
Residential, agricultural, or light commercial — we assess your structure and climate to deliver the right spray foam solution, every time.
Onalaska is a growing community situated between the Mississippi River lowlands and the bluffs that rise sharply to the east. That geography means buildings here face real moisture challenges from below and significant cold-air exposure from above. In winter, uninsulated or under-insulated structures lose heat fast. In summer, humid air infiltrates and condenses inside wall cavities.
For Onalaska residents and business owners, this is not just a comfort issue — it is a structural one. Moisture trapped inside walls, attics, or crawl spaces leads to mold, rot, and long-term damage. And every month your building leaks heat or cool air is another month of unnecessary energy spending.
Our insulation systems are designed to:
Higher heating and cooling bills
Uncomfortable indoor temperatures year-round
Moisture buildup and increased mold risk
Long-term structural damage from air and water infiltration
Poor sound control between rooms and floors
You deserve insulation that performs.
Moisture control and full air sealing for shops, barns, equipment storage, and farm structures. Spray foam is the single most effective insulation system for pole barns in Wisconsin — and we install it right.


Warehouses, retail spaces, offices, and industrial buildings requiring high-performance insulation that meets code, controls moisture, and reduces operating costs.

Attics, walls, crawl spaces, basements, rim joists, garages, and new construction homes throughout Onalaska and surrounding areas. Every application is tailored to the building's specific needs.

2-pound closed-cell spray foam for superior air sealing, vapor control, moisture resistance, and added structural rigidity. Ideal for exterior walls, crawl spaces, basements, and pole barns.

Half-pound open-cell spray foam for excellent sound control, cost-effective air sealing, and interior wall insulation. A smart solution for attics, interior partitions, and budget-conscious projects.

Your home should stay warm in winter and cool in summer — without you constantly adjusting the thermostat. Your pole barn shouldn't have a moisture problem. And your utility bills shouldn't keep climbing. Driftless Foam's professionally installed spray foam insulation fixes all of that, making your structure tighter, stronger, and more energy efficient. This is insulation built to work as hard as you do.

Waiting on insulation upgrades only makes things worse. Air leaks, moisture, and heat loss don't go away on their own — they quietly strain your HVAC system, rack up repair bills, and weaken your building over time. Acting now with professional spray foam insulation protects your investment and stops bigger, costlier problems before they start.
Driftless Foam works throughout the Onalaska area, serving both newer developments and established neighborhoods. We know local construction styles, common problem areas in regional buildings, and what type of spray foam performs best for each application. Whether you need attic insulation in a ranch home, basement rim joist sealing, or full insulation for a new commercial build, we deliver the right solution.
